SHEAF-LOADER.

To all whom it may concern:

Be it known that I, JOHN Tnrscvr BERG- MAN, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in sheaf-Loaders, of which the following is the specification.

The invention relates to a hay and sheaf loader and the object of the invention is to provide an inexpensive, easily operated and efficient machine which will gather up sheaves from the ground and elevate them to a position where they can be readily dumped into a wagon, the machine being readily controlled by a single operator.

It consist essentially in a portable frame mounted on a pair of carriage wheels and a drive wheel, a pick up conveyer at the forward side of the machine, a cross conveyer adjoining the rear end of the pick up conveyer and having a portion thereof horizontally disposed and a portion thereof inclined, a rotatable sweep or spiked wheel adjoining the forward end of the pick up conveyer, an adjustable pan or gatherer pivotally secured to the forward end of the pick up conveyer, controllable means for operating the conveyer and the sweep and means for adjusting the pan, the parts being arranged and constructed as hereinafter more particularly described.

Figure 1 is a front view of the complete machine. Fig. 2 is a plan view of the same. Fig. 3 is a plan view of the frame and the various shafts carried thereby the conveyer being removed. Fig. 4 is an enlarged detailed side view of the drive wheel and adjoining parts. Fig. 5 is a vertical sectional view through the drive wheel. Fig. 6 is a vertical sectional view through the machine, the section being taken in the plane denoted by the line YY Fig. 2.

In the drawings like characters of reference indicate corresponding parts in each figure.

1 represents a substantially rectangular main frame comprising front and rear beams 2 and 3 and side beams 4 and 5, the side beams extending beyond the front beam 2.

6 and 7 represent suitable carriage wheels rotatably mounted on stub axles 8 extending from the beams 4 and 5.

9 represents the main shaft of the machine which is rotatably mounted in the extending ends of the beams 4 and 5.

1 is a g ound or drive Wheel having the Specification of Letters Patent.

hub thereof fixed on the shaft at a point adjoining the tongue 11 which is secured permanently to the frame and extends forwardly therefrom.

l2 and 13 are similar opposing downwardly inclined side pieces permanently carried by the frame and forming supports or bearings for the ends of the pick up conveyer shafts l4 and 15.

The shafts carry pairs of chain wheels 16 and 17 connected by chains 18. The chains are connected with cross bars 19 fitted with extending spikes 20.

The pick up conveyer is adapted to gather the sheaves from the ground and deposit them on an endless cross conveyer 21 comprising an endless belt 22 fitted with suitably spaced cross slats 23 and carried by endless chains 24 and 25 the chains being mounted on pairs of chain wheels 26 and 27 carried by end shafts 28 and 29 and an intermediate shaft 30. The shafts 28 and 30 are rotatably mounted in suitable bearings carried by the beams 2 and 3 while the shaft 29 has the ends thereof mounted in the upper ends of angularly disposed side shields 31 and 32 which extend from the frame and above the wheel 6. The brace bars 33 support the overhanging ends of the shields from the frame.

34 is a back wall or guard plate carried by the frame and continuous with the inner end of the shield 31.

35 is a side wall or guard plate mounted on the beam 5 and continuous with the side piece 13 and having the rear end thereof butted up against the back guard plate.

The rear end of the side piece 12 abuts up against the inner end of the shield 32 to which it is also secured.

36 is a deflecting plate permanently secured to the side pieces 12 and 13 and overhanging the horizontally disposed portion a of the said conveyer.

The shaft 9 is fitted with a loose sleeve 38 carrying at the opposite ends a beveled pinion 39 and a wheel 40, said wheel 40 having the teeth 41 thereof meshing with the toothed wheel 42 mounted on a stub shaft 42 carried by the side piece 12. The chain wheel 42 is coupled to the toothed wheel 42 and operates also on the stub shaft. This chain wheel is connected by a chain 42 with a chain wheel 15 located on the end of the shaft 15. The bevel wheel 39 meshes with the bevel pinion 43 permanently lo-- cated on the extending end of the shaft 30. The sleeve is prevented from end play by a collar 38.

44 and 45 are further chain wheels on the shafts 30 and 28 and 46 is a chain connecting them.

47 is a gathering pan pivotally secured to the forward ends of the side pieces 12 and 13 and having the ends thereof turned upwardly at 48 to prevent material from escaping over the ends of the pan. One of the flanges or upturned ends of the pan" is cut away to admit a more or less upright shaft 49 rotatably mounted in the end of the pan and provided at the upper end with a pulley 50 which is connected by a rope, cable or other such drive with a pulley 51 located on the end of the shaft 14 Which, it will be no ticed, extends beyond the side piece 13.

52 is a spiked sweep or gathering wheel fixed on the lower end of the shaft 49 adjoining the upper face of the pan. The pan is supported adjustably by a lever 53 pivotally secured at 54 to the tongue and having the forward end thereof pivotally connected to a supporting bar 55 permanently secured to the pan. The lever is located within convenient range of the operators seat 56 mounted on the tongue.

The chain wheel 40 is supplied with a number of concentrically arranged openings 40 designed to receive the extending end of a dog 57 pivotally secured at 58 to lugs 59 extending from the hub of the wheel 10. The opposite end of the dog is forked at 60 and spans the shaft 9 clear of the hub of the wheel. A lever 61 is pivotally secured at 62 to the side of the tongue and has the lower end thereof forked at 63 to span the shaft 9 at a point adjoining the forked end of the dog. A spiral spring 64 is connected to the dog and the hub and tends to hold the dog normally against the face of the Wheel 40 or in one or other of the openings 40. The upper end of the lever 61 is located within convenient range of the drivers seat.

When the machine is in use it is drawn over the ground by draft animals attached to the tongue 11, the ground wheel 16 ro tating as the machine advances. If the driver desires to pick up sheaves on the ground he adjusts the pan by means of the lever 53 and directs the animals so that the sheaves will be picked up by the pan. The sheaves are passed over the pan onto the pick up elevator which passes them to the cross elevator where they are elevated so that they can be dumped onto a wagon which accompanies the machine the wagon being driven so that it will have a position directly beneath the upper end of the cross conveyor.

It is here to be noticed that as shown in the drawings the dog will be held by the spring in one or other of the openings 40 until displaced by the lever 61. Accordingly the pick up conveyor will be rotated by the wheel 40, the cross conveyer will be operated by the bevel pinion 43 and the sweep ill be actuated by the connection 50. If the operator desires to stop the conveyers and sweep he has simply to draw the lever 61 toward him which motion causes the lower end of the dog to be depressed and the upper end to be withdrawn from the opening 40. A quadrant could be supplied with this lever so that it could be set in two positions, the one position in which the dog is engaged and the other the position in which the dog is disengaged with the wheel. I have not considered it necessary to show or detail this in the drawings as the con struction is well known and its application would not amount to invention. It is remarked however that if a quadrant is supplied the horizontal position of the dog is reversed, that is to say the dog is held normally out of engagement with the wheel 40 so that as the machine was passing over the ground and not picking, up sheaves the draft animals would not have the additional weight of the drive. The operator could throw in the dog when he was about to approach the sheaf or sheaves. The sweep is provided to gather in sheaves slightly to the side of the pin as will be readily understood.
